Two others were arrested and the homeowner was taken to the hospital.
A homeowner in Summerfield, Florida, whose name has not been released by the Marion County Sheriff's Office, acted quickly when four men invaded his home last week. According to police, the men were looking for marijuana and firearms.
The intruders were all armed, prompting the homeowner to resort to his AR-15 rifle in self-defense.
He killed two men, who were identified as Nigel Doyle, 22, of Summerfield, and Keith Jackson Jr., 21, of Ocala. The other home invaders would be detained nearby, and were identified as Robert John Hamilton, 19, of Ocala and Adam Rodriguez, 22, of Belleview.
Authorities first received a call at 8:21 p.m. Wednesday night of multiple shots fired.
Upon arrival, Sgt. Micah Moore found Doyle on the ground outside the house with a fatal gunshot wound and a shotgun next to him. Once authorities entered the residence they found Jackson and the 61-year-old homeowner.
Jackson was lying dead on the dining room floor with a "Jason" mask on his head and semi-automatic pistol near his body.
The homeowner was injured in one of the bedrooms.
